Kepler-1465 b

BarrenMarginal1170 light years awayFound 2016

Kepler-1465 b, from the NASA Exoplanet Archive (found 2016). Measured: 3.78 Earth masses, 0.194 AU, a 4726 K K-type star. Composition inferred from a measured bulk density of 0.68x Earth's — too light for bare rock, so a large fraction of water and ice, with an assumed 24-hour day — rotation cannot be measured for exoplanets. Note: TerraForge comes out at 467 K against the archive's 668 K, because it models stars by spectral class, and Kepler-1465 is not an average K-type.

Barren

Magnetic FieldHigh Activity
Why is this a Barren?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 3.8x EarthTemperature: 467K

The TerraForge exoplanet catalog: 5,572 real exoplanets run through the simulation, with a search field and rendered worlds grouped by type

New: The Exoplanet Catalog 🔭

Every confirmed planet NASA has measured well enough to build — 5,572 of them — is now in here, and none of them arrived with a label. Their real mass, radius, orbit and star go through the same simulation that runs everything you make, and it decides what each one is: gas giant, lava world, ocean, ice. Sixteen come out Earth-like. Find TRAPPIST-1e, stand on its surface, and see what a red dwarf's light actually looks like from the ground.
